MACHINE FOR FORMI-NG AND HOOPING BARRELS.

SPECIFICATION forming part of Letters Patent No. 454,764, dated June 23,1891. Application filed February l0, 1890. Serial No. 339,869. (Nomodel.)

To all whom it may concern:

Be it known that I, JAMES PLEUKHAEP, a citizen of the United States,residing at Oolumbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Machines for Forming andHooping Barrels; and I do hereby declare the following to be a full,clear, and exact description of the invention,such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to a machine for hooping and forming barrels, andhas for its object the provision of a machine that will head, form, andhoop barrels in a simplehpicient, and convenient manner. A A furtherobject of the invention is to provide a machine for making barrels ofthe following description: Staves of sawed lumber, a kdefinite number toeach barrel, say sixteen staves planed straight on inside and crozed andchamfered; staves turned shape of barrel on outside by my machine (seePatent No. 415,5585) staves all of equal length, width, and thickness,heads also of equal size. Thus the barrels will be all of a definitesize and will hold equal measurement.

The machine consists, essentially, in a series of concentric jaws, andthese jaws are provided with hoop carriers and drivers'. There is a setof these jaws for each end of the barrel, one for each end of eachstave. These jaws are furnished with long leverarms that are pivoted onmovable disks which are operated by a screw-shaft. These leverjaws aremade to swing on their pivots by means of a sliding disk (also operatedby screw-shafts) in connection with the outer ends of the lever-arms.

. The improvement further consists of the novel features which will behereinafter more fully described and claimed, and which are shown in theannexed drawings, in which- Figure l is a side view, partly in sectionand parts being broken away, of one end of a machine embodying myinvention. Fig. 2 is a view similar to Fig. l of the other end of themachine, showing by dotted lin'es the relative arrangement of the sideshafts for moving the plate which operates the outer ends of thelever-arms of the jaws. Fig. 3 is an end view of the jaws, showing therelative arrangement of the ring for springing the ends of the barreland-the hoop-support. Fig. 4 is a section on the line X X of Fig. 2,looking to the left. Fig. 5 is a section on the line Y Y of Fig. 2,looking to the right. Fig. 6 is a plan view, partly in section and partsbroken away, of one end of the machine, showing the relative arrangementof the parts and the instrumentalities for operating the disk and platewhich control the movements of the lever-arms.

A is the barrel in cross-seetion. a is a temporary rest for barrel.

o. is a single stave. Staves are formed into a cylinder and securedtemporarily previous to operations of this machine.

' a is a barrel-head.

. B is a sliding head-plate, having shank B which works in the socketB2, secured to the frame of the machine.

b is a screw at center' of plate B for holding head a thereto.

b b2 b3 are levers and eccentric for throwing head-plate out of way whenbarrel is finished.

O represents hoops. l

o represents fingers for drawing hoops 0H the carrier-arms.

c are carrier-arms chine-frame.

D is a flanged ring, and CZ a flange thereon. This ring serves to squarethe barrel. (See left-hand side of Fig. l.) Its relation to jaws iscontrolled by flange d.

d is a slot in jaws F in which ring works.

' CZ is a spring to relieve the machine of any sudden jar inthe squaringup of the barrel.

E is a self-adjusting hoop-driver.

e is a tension-spring for controlling same hoop-driver.

e is a nut for iixing number of pounds tension or pressure to be appliedon spring for driving hoop.

e is a regulating-screw for limiting t-he inward movement of the outerend of the hoopdriver.

F are the lever-arms of the jaw.

f is a shoe on the end of each jaw F to force down the stave upon heada.

f is an adjustable slide at the rear end of the lever-arm.

f is a double-threaded screw for controlrigidly secured to ma- `ingadjustable slide f. l

f is a pivot of arm F.

h is a rubber cushion or packing to take shock in stopping and removeany strain on the levers F which might be caused by overpressure. If informing 'the barrel the operator should allow the disk H to run too far,a strain would be caused upon the levers which is obviated by theyielding nature of the packing z.

G is a movable disk carrying the lever-j aws threaded for screw-shaft.

H are sliding plate-rests and slides on central screw-shaft K.

I are side screw-shafts horizontal and parallel with central screw-shaftand on same plane with it.

'L' is a box-nut working on shaft I and connected rigidly with thesliding plate H.

'11 are standards supporting shaft I. There are two of these side shaftsI, one on each side of the machine, as shown in Fig. 6.

K is a central screw-shaft carrying the movable disk G, lever-jaws F,(Sac.

la 7e are standards supporting the central screw-shaft K.

L isadrive-pulley receiving its motion from any suitable source ofpower.

M is a shaft carrying drive-pulley L, runs the entire length of themachine, and is provided at each end (only one end being shown) with agear-wheel m, which meshes with idler m', which meshes with gear-wheelm2 on the screw-shafts K.

N is a small or rather short shaft vcarrying idler 'm'.

'n' are boxes for idler-shaft N.

M are boxes carrying the long shaft M.

O is a drive-pulley operated by any motivepower similarly todrive-pulley L.

P is a shaft, running the entire length of the machine, carryin g thedrive-pulley O, and provided at each end of the machine with thegear-wheels P, which mesh with idlers P2, and these with other idlersP3, and these with gearwheels P4 P5 upon the side screw-shafts I.

Ps are boxes carrying the long shaft P.

R are idler-shafts, with their boxes r. The left hand of Fig."1 showsfull view of inner end of one arm, with cross-sections of disks, &c. Thejaw is here closed and one hoop just on barrel.

v. Fig. 2 shows rear end of one arm and crosssection of operating-plate,and the relative arrangement of the side screw-shaft by dotted lines.The main screw-shaft, dac., are also shown running back, all as a sideView, to the gearing mechanism running the screwshafts.

Operation of machine: Jaws open and back to farthest extremity. (Seeleft-hand side of Fig. l.) Hoops, threeor more, are placed on thecarrier-arms c at each end. Heads are fixed upon the head-plates B bymeans of the small screws b, (each end of the machine.) The staves whichhave already been set up into a cylindrical form on another machine arenow placed upon the temporary rest a a. By means of the mechanismdescribed the center shafts (at each end of machine) arerevolved,carrying the disks G forward, and with them the lever-jaws,until the rings D are brought into contact with the ends of the staves,squaring the barrel, as shown in Fig. 1, on the left-hand side. Thismovementis then stopped and the surplus of power is taken up by thesprings d. During this movement the lingers c keep the hoops in theirproper relation to the jaws and hoop-drivers. mechanism described theshafts I are revolved, (at each end of the machina) carrying thesliding-plates H forward, thus causing the lever-jaws to turn upon theirpivots and forcing the jaws inward, and thus pressing the staves downupon the heads and barrel shape. This movement is now stopped and theforward movement of the disk G,with its arms, is resumed. The nose orshoe f slides up the face of the stave and the hoops are carried to anddropped their proper places by the hoop-driver E. This movement of theshoe f up the incline or bilge of the barrel is provided for by means ofthe adjustable slide f (which has the reverse of the form outside of thestave) sliding over the now stationary head. The hoop-drivers areprovided with the tension-springs e, (which are regulated by the nutse,) by which a given number of pounds pressure may be used in theforcing of each hoop. When a pressure equal to the amount xed isreached, the hoopdrivers turn upon their pivots and the hoop is dropped.The driver passes or drags over it, carrying the next one to its place,dac. The barrel is now complete and is taken out, leaving the machineready for the next. The mechanism operating the side screw-shafts isfirst reversed, carrying the disk H backward and opening the jaws. Thenthe mechanism operating the central screw-shaft is next reversed,carrying the disk Gand the jaws with it backward until the jaws haveentirely cleared the barrel. By means of the eccentric and levermechanism described the headplates B are thrown back out of the Way. Thebarrel may now be removed, finished complete, the head-plates thrownforward again, and all is ready for another barrel.

Having thus described my invention, what I claim, and desire to secureby LettersPatent,
